As an alternative to the conventional Impco Model 425 (4.5" high) or Model 300 (6" high) dual fuel conversions for V8 carbureted engines, a low profile (3.5" high) dual fuel system is available for V8 engines having a 5-1/8" airhorn. Because Technocarb focuses only on dual fuel systems for EFI engines, this system is offered instead through Raso Enterprises and does NOT come with Technocarb's warranty. Essentially, the V8 Dual Fuel Venturi Conversion is based on Technocarb's off-road 4bbl carburetor kit with their TBI mixer replacing the 4bbl carburetor.

For liability reasons, I have temporarily removed kits that are not supplied complete by manufacturers. The V8 Dual Fuel Venturi Conversion kit is for carbureted vehicles only and you require a TBI kit.

The kit you need is PN DP-GM74-87-97, which retails for $1928.57. I have not added this item to my ecommerce site yet.
